Estate agents can sell you a house and help you with moving it. That's also what they do in Corruption X. They can redecorate your house and they can even move your house to various places in Corruption X.
Estate Agents can be found in Seers' Village (north-east of the bank), Falador (between the furnace and the east bank), Ardougne (west of the east bank) or in Varrock (east of the castle). There's a picture of the estate agent's location in Varrock contiguously. Estate agents can be recognized by the -symbol on the mini-map.
